Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747766, here are decompositions:

7 + 8747759 = 8747766
19 + 8747747 = 8747766
23 + 8747743 = 8747766
29 + 8747737 = 8747766
43 + 8747723 = 8747766
89 + 8747677 = 8747766
113 + 8747653 = 8747766
149 + 8747617 = 8747766

Showing the first eight; more decompositions exist.
